The CAVIAR machine was used in conjunction with a CAMAC system, consisting of a set of I/O modules assembled in a 19" crate. Some of the CAMAC-modules (for instance, analog-to-digital converters) would directly be connected to measuring devices, while another module would give access to a host (mainframe) computer through a high-speed link. The CAVIAR uses a Motorola 6800 microprocessor with 32 kB of solid-state RAM. In 29 kB EPROM the BAMBI (BASIC-like) interpreter is stored. Using the BAMBI graphics commands, graphs and histograms can be shown on the built-in miniature monitor screen. An alphanumeric terminal is connected to CAVIAR for programming and entering commands. The Super-CAVIAR (shown in the picture) is an enhanced version of CAVIAR with 64 kB RAM, 84 kB EPROM and other improvements. </abstract> </front> <article-type>MICROCOSM</article-type> </article> </articles>
